DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is detailedly explained as following inembodiments with appended drawings to facilitate your reviewersunderstanding the inventive characteristics, contents, advantages, andachievable effects thereof, in which the appended drawings only for thepurpose of schematizing and supporting the specification may not be trueproporation and precise configuration as embodied invention, and shouldnot be a reason thus limiting the embodied scope of the invention.

Referring now to FIG. 1 to FIG. 7, the preferred embodiment of thepresent relates to a multifunction safety mask with earmuffs clipincluding a front hoop ring (10), a brim body (20), a back hoop ring(30), a top belt (40), and earmuffs (50).

A connection portion (11) is placed at each of the two sides of thefront hoop ring (10), in which each connection portion (11) is placedwith a brim hinge joint part (111), a back hoop ring hinge joint hole(112), and a top belt hinge joint hole (113), and an earmuffs clampgroove (114) is placed at the top side of each connection portion (11).

The two sides of the brim body (20) are hinged at the brim hinge jointpart (111) placed at the two sides of the front hoop ring (10)respectively, and a lens (21) is buckled at the front edge of the brimbody (20).

The two ends of the back hoop ring (30) are buckled at the back hoopring pivot holes (112) placed at the two sides of the front hoop ring(10) respectively.

The two ends of the top belt (40) are buckled at the top belt hingejoint holes (113) placed at the two sides of the front hoop ring (10)respectively.

The earmuffs (50) includes two earmuffs bodies (51 a), (51 b) connectingwith a link plate (52) between them, in which the two sides of the linkplate (52) enter and buckle in the earmuffs clamp groove (114) placed atthe two sides of the front hoop ring (10), the link plate (52) is placedacross user's head when weared; thus the musk of the present inventionnot only is stably weared on user's head, but also prevents the userfrom noise damage with the earmuffs (50) stably buckled on the musk.

The multifunction safety mask with earmuffs clip disclosed by thepresent invention further includes a pair of angle adjustment components(60) of the brim body (20), in which the angle adjustment components(60) are placed between the brim body (20) and the front hoop ring (10)and cover positioning column (12) protrusively placed at the brim hingejoint part (111) of the front hoop ring (10) respectively, and apositioning pin (61) protrusively placed at each angle adjustmentcomponent (60) is inserted in positioning hole (22) of the brim body(20); and a central perforation (62) is through placed at the center ofthe angle adjustment component (60), and one side of the angleadjustment component (60) is depressed with a ring groove (63)encircling the center of the central perforation (62) forcorrespondingly allowing one positioning column (12) of the front hoopring (10) to extend into the ring groove (63) and being protrusivelyplaced with a positioning convex portion (631) along the radialdirection of the ring groove (63); thus when the brim body (20) and thefront hoop ring (10) perform relative rotation adjustment, if thepositioning column (12) leans on the positioning convex portion (631) ofthe ring groove (63), the brim body (20) and the front hoop ring (10)are driven to perform relative rotation continuously, so as to positionthe adjustable rotation angle of the brim body (20) and the front hoopring (10).
